I do wonder how much lore you've actually read, if only because Eldar have always been like that and it hasn't much to do with 'magic', but rather their physiology.


[hider=Eldar Stuff]The most fundamental difference can be seen when the Eldar move, for they each radiate an inhuman elegance and poise. This is especially evident in the sinuous grace with which they fight and the dexterity with which they field their weaponry. Every gesture is laden with subtle intent, and their reflexes are dazzlingly fast. 

A casual, languid gesture can end in a pinpoint thrust should the necessity arise. On closer inspection, every aspect of the Eldar physiology betrays their alien nature. Their hearts beat at twice the speed of a human's, and their minds race through possibilities and process emotions so fast that even the so-called geniuses of human history appear dull by comparison. 

Even their lives are greater in span -- the Eldar enjoy lives of rich sensation and wonder that can stretch over a millennium, unsullied by illness, frailty or disease. All Eldar can manipulate mental energies to a degree. Each is psychic to one extent or another; it is said the ancient Eldar could read thoughts at a glance, whilst those who trained their minds for war could crush a foe's weapon with a simple narrowing of their eyes. Even the complex technology of their race is based upon psychic engineering, the manipulation of and even creation of matter using mental energies alone. But such raw power has its price.[/hider]


So, while they do make use of psychic abilities, they are more so just extremely fast due to their biology and evolution (unless you also count Warlock and Farseers, who can usually read the future anyway); never seen a problem with it myself, in almost every written piece of lore about them they are shown and known to be quicker than pretty much anything else.
